W elcome to our early spring edition of AM&P, which focuses on aerospace and includes our thermal spray and heat treating newsletters. Although I’m looking out my window at snow flurries under the Dome, spring is just around the corner and so are our two spring events—AeroMat (May 6-8) in Reno, Nevada, and ITSC (May 26-29) in Yokohama, Japan. New this year, we will be placing copies of AM&P in every single registration bag— another step in more widely disseminating the latest techni- cal trends taking place across the materials science universe. We hope many of you will be able to attend one or both of these conferences. So much is happening these days with regard to aerospace inventions. In this issue alone, we’re covering several key materials developments. For starters, we have two in-depth feature articles about novel materials that hold promise for aerospace applications: One talks about producing lightweight, high strength aluminum alloy-SiC composites (p. 16) while the other discusses MAB phase- based nanolaminates (p. 22). In addition to these technical articles, we’re including some fascinating news items on leading edge research in aerospace materials. For example, a team in Hong Kong reports developing a newway to produce high-entropy alloys (p. 8) using a formula of complex nanoparticles that allows both high strength and ductility to coexist, a previously elusive goal. Another group at the University of Houston has created a durable silicone polymer they say is capable of repel- ling ice from any surface—including airplane wings (p. 7). They report that this new coating can be applied as a spray and will last more than 10 years. Finally, be sure to check out our cover story in the HTPro newsletter (p. 58), a technology update from GE Additive on the heat treatment of additively manufactured met- al parts. One of GE’s greatest achievements is its 3D-printed fuel nozzle tip for the LEAP aircraft engine and this past October, the company celebrated printing its 30,000th unit. In other aerospace news, Boeing successfully accomplished the first test flight of its autonomous passenger air vehicle (PAV) on January 22. Imagine a driverless Uber with wings soaring over the gridlock in cities like Los Angeles and New York. According to the Boeing press release, Boeing NeXt, which leads the company’s “urban air mobility” efforts, used Aurora Flight Sciences (a Boeing subsidiary) to design and develop the electric vertical takeoff and landing (eVTOL) aircraft. The PAV prototype completed a controlled takeoff, hover, and landing, which tested the vehicle’s autonomous functions and ground control systems. Future flights will test forward, wing-borne flight, and the transition between vertical and forward flight modes. According to Boeing, the transition phase is typically the most significant engineering challenge for any high-speed VTOL aircraft. At AM&P, we enjoy celebrating technology milestones like the ones included in this issue. Drop us a line to let us know what you’d like to learn more about. In the meantime, we hope to see you at one of our spring events. frances.richards@asminternational.org AUTONOMOUS AIR VEHICLES ON THE RISE Prototype of Boeing NeXt, an autonomous passenger air vehicle.
